Although, it is sort of inaccurate because I bought a majority of my games when they were discounted and I never bought the Valve complete pack but I just happen to own all the games in it I guess (blame the orange box)

I didn't pay for Bioshock 2, or Dragon Age. Either my brother or friend who I share the account with did. I bought mount and blade when it was $5, GTA4 when it was $8, World of Goo when it was $2 (don't think this was even a discount, I think it was just that cheap back then) and like I said I didn't pay for the valve complete pack. The Orange Box is just amazing. ^^
